Hi,
I'm implementing a forum using Seam, <rich:dataTable> and <rich:dataScroller> pretty much the same way as described here: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4112998
My forum allows categorizing topics and provides a <h:selectOneMenu> to filter topics by their categories. Basically it works like this: The user selects an item from the <h:selectOneMenu>, which causes an ajax request updating the content of the <rich:dataTable> that provides the topics.
The problem is that the dataTable's dataScroller gets updated before the new value of the selectOneMenu is applied, which results in a flawed presentation of the number of rows (it always displays the quantity for the previously selected category).
Here's the JSF code:
<div>
show topics:
<h:selectOneMenu value="#{forumEntryFilter.selectedCategory}">
<s:selectItems value="#{forumEntryFilter.categories}" var="category" label="#{category}" />
<a:support event="onchange" reRender="forumList" />
</h:selectOneMenu>
</div>
<rich:dataTable value="#{forumEntryDataModel}" var="topic" rows="20" id="forumList">
<rich:column style="width: 70%;">
...
</rich:column>
<rich:column style="width: 30%;">
...
</rich:column>
<f:facet name="footer">
<rich:datascroller id="scroller" />
</f:facet>
</rich:dataTable>
Any help is appreciated!
